Simplify command structure

[danasf]

Currently you need to type:

led-bot show-text <your text> led-bot show-image <your image url>

To display things. Marcus and I discussed simplifying things. Perhaps we could do something like:

led-bot image <your image url> led-bot <your text> ?

Seconded the default behaviour for the text.
For the images (and maybe to text in some extent) should we some way of passing commands on how the image/text is shown? Like changing scroll direction (or removing scroll), inducing delay etc. or should we just have something like --direction:up --speed:slow?

also, we could give the led-bot a better name. :smile_cat:

@marqsm #8 is somewhat similar, and sounds like a good idea.

I'll do something about this
